Learning outcomes

MODULO BIOINGEGNERIA ELETTRONICA Obiettivi formativi: Fornire una panoramica della bioingegneria elettronica con particolare riferimento alle applicazioni e tecnologie biomediche. Fornire gli strumenti per la conoscenza delle principali apparecchiature di laboratorio e in particolare i concetti base delle grandezze fisiche e teoria dei segnali, trasduttori e bioimmagini.

MODULO FISICA APPLICATA A MEDICINA E CHIRURGIA Obiettivi formativi: Il Corso è finalizzato a fornire, allo studente, le conoscenze fisiche di base, tenendo in particolare considerazione quelle successivamente utili alla comprensione ed allo approfondimento di problematiche biomediche.

MODULO MISURE ELETTRICHE ED ELETTRONICHE Obiettivi formativi: Fornire una panoramica sui fondamentali componenti e circuiti elettronici con particolare rilievo ai riferimenti ed applicazioni alle apparecchiature impiegate dai laboratoristi e specifica enfasi alla catena di rilevamento di grandezze fisiche, trasduzione in grandezze elettriche, loro conversione in segnale digitale.

MODULO STATISTICA MEDICA Obiettivi formativi: Il corso si propone di insegnare agli studenti a: - valutare l'affidabilità delle misurazioni effettuate in ambito biomedico; - descrivere in modo appropriato le informazioni raccolte su un collettivo di pazienti; - calcolare la probabilità di uno o più eventi;
